It's the outermost sector of the area of the disc that contains data
as opposed to containing meta-data.  The TOC declares these
boundaries.

It makes sense that if the CDROM is, itself, shifting samples because
of a queueing mechanism that it is impossible to get those last few
bytes.  It's also possible that a given drive allows reading past user
data (figuratively or literally) as a way of flushing those bytes, but
I also know that a large number of drives will lock up or lose command
sync if you try it.

The original cd specs said drives were allowed to do things like that
(offsets to seeking), so long as the accumulated error was less than a
second (thus the mandated two seconds of silence between tracks).
